Karl Lagerfeld, Alexander McQueen Debut High-Fashion Websites

In addition to dressing Hollywood's hottest stars for the red carpet and staging Fashion Week's most talked-about runway shows, two fashion powerhouses have launched (and revamped) some of the chicest websites we've ever seen.

Karl Lagerfeld, who's BFF with Blake Lively, Rachel Bilson and Diane Kruger, just debuted World of Karl, where he shares his favorite hot-spots (The Mercer in New York City; his bookstore 7L in Paris), publications and quotes.

Alexander McQueen's website has been redesigned to incorporate the British brand's hip McQ label (Emma Watson and Anna Kendrick are fans).

The coolest new feature is the digital scarf boutique where you can check out McQueen's iconic skull scarves in a ton of color combinations, plus exclusive prints. You can also view runway videos and an exclusive backstage film of the incredible McQ Fall 2012 presentation.
